The visa is tricky in the United States.
As far as Bovada goes their customer service is the best, they are prompt at answering emails, and they have their customer service telephone number posted you can use as well, they are extrememly helpful.
The sngs and cash tables are soft and easy to build on.
There cashouts are usually quick

Now the downside,
Filling up multitable sngs are slow like Carbon.
At all of the tables you are a number not a name, so note taking on anyone is impossible. your number changes and corresponds to when you registered for a game. (if you registered 3rd for a sng, you will be #3)
